[Bug 986806] Re: swap not activated after choosing 'use whole disk' with encrypted home

[Akhila]

I tried reproducing the bug with Quantal running on VirtualBox with disk space 10.7GB .
jibel's words echo exactly what I experienced.
While rebooting it said, 


"The disk drive for /dev/mapper/cryptswap1 not ready yet or not present.
Continue to wait or Press S to skip mounting or M for manual recovery."


Within a minute system rebboted without any error.
On booting, like you suggested, I executed "free -m"
The result is:


swan at swan-VirtualBox:~$ free -m
             total       used       free     shared    buffers     cached
Mem:          1003        620        382          0         24        338
-/+ buffers/cache:        257        745
Swap:         1021          0       1021 


Though, "sudo sfdisk -l" produced an error:
swan at swan-VirtualBox:~$ sudo sfdisk -l
[sudo] password for swan:

Honestly, I didn't understand that.

Title:
  swap not activated after choosing 'use whole disk' with encrypted home

Status in “ubiquity” package in Ubuntu:
  Incomplete

Bug description:
  I already had 12.04 installed on this pc, so for partitioning I choose "remove and reinstall Ubuntu 12.04". 
  I choose to install with encrypted home, which means the swap also got encrypted. Installation went fine, but afterwards ubuntu did not recognise the swap partition.
